Description

Euroform demolding tool {A Device for Extracting Separators or the LikeEmbedded in a Concrete Structure}

The present invention relates to a Eurofoam type demolding tool, and more preferably Euroform (form) fixedly installed on the inside and the outside to cast concrete structures such as retaining walls or walls at civil, building, and landscape construction sites. After pouring concrete into the concrete, it is to make it easy and easy to demould euroform from the concrete surface after the concrete is cured.

In general, EURO FORM is a standard formwork that can be assembled and installed quickly and efficiently in the field of civil engineering, architecture, and landscaping. It is mainly used to construct concrete structures that are vertically erected such as retaining walls, walls, and columns. It has been widely used to install concrete on the inside and outside, and then fix it with a pre tie.

The Euroform is equipped with a rectangular steel frame in which pin holes for assembly are drilled at equal intervals and heterogeneous panels installed by smoothly fixing on one surface of the steel frame so as to face each other at a corresponding construction position and to a pin hole. It is designed to be assembled and installed easily and precisely by the fixing pin to be fitted, so that the concrete structure can be constructed more efficiently.

On the other hand, such a Euroform has been performed by a worker using a demolding tool (called 'Paru' in the field) after the construction of the concrete structure, the general demolding tool used in the field is used to demold the Euroform It is not known to be suitable.

That is, the conventional demolding tool 100 has a bag member 110 made of a rod shape as shown in FIG. 1 and a wedge shape formed in a wedge shape at a free end bent at a right angle to one side of the bag member 110. Consisting of the blade 120 and the inclined deformed blade 130 formed in a wedge shape at the free end bent inclined to the other side of the bag member 100, the action force applied from the bag member 110 is bent and inclined deformed blade Since it is a simple structure that is directly exerted by (120) (130), it came with a number of problems when demolding.

First, when the working space is not secured without gaps between the euroforms 200, as shown in FIG. 2, the worker is inclined to demolding the demolding tool 100 between the euroform 200 and the euroform 200. Since the blade 130 is forcibly inserted, and the other one of the euroforms 200 is used as a support point, the other one of the euroforms 200 is lifted up. There was a problem reducing.

Second, when the working space is secured between the Euroform 200, as shown in Figure 3, the operator bending the demolding blade of the demolding tool 100 between the Euroform 200 and the forming surface 300 of the concrete structure Since the 120 is forcibly inserted and the Euroform 200 is lifted with the forming surface 300 of the concrete structure as a supporting point, damage to the forming surface 300 of the concrete structure during the demolding operation greatly degrades the construction quality. Not only that, but also damage the plywood.

Third, since the working conditions for demolding the euroform 200 from the forming surface 300 of the concrete structure are very poor, the worker had to bear the inconvenience of performing the demolding work by applying excessive force, and a lot of unnecessary work. There was a problem that takes time.

In order to solve this problem, Utility Model Registration No. 20-196704 "Euroform-type demolding tool" has been developed and published. However, the above configuration is a grounding roller or handle portion which is formed on the supporting member which supports it when demolding the euro form when the catching protrusion of the hook member formed at the upper end of the handle portion is inserted into the pin hole of the euro form so as not to damage the euro form. If the wedge part installed integrally in the rear is damaged during use, the entire demolding tool must be replaced, which causes a burden on the user.

The present invention has been devised to solve the above problems, it is installed on the inside and outside to install concrete structures, such as retaining walls or walls at the site of civil engineering, architecture, landscaping construction is fixed by the pretai When it is cured by pouring concrete with Eurofoam, it aims to be able to use it for a long time while replacing the ground roller of the demolding tool for demolding Eurofoam simply and easily from the concrete surface.

That is, even if the grounding roller mounted on the handle end of the demolding tool or the wedge installed at the rear end is damaged during use, the purpose of the present invention is to replace and reuse only the damaged section without purchasing the entire demolding tool.

Referring to the configuration of the subject innovation having the above object based on the accompanying drawings as follows.

Hereinafter, the most preferred embodiments of the present invention will be described with reference to the accompanying drawings so that those skilled in the art may easily implement the present invention.

Figure 4 is a perspective view showing a demolding tool for demolding the flow path of the present invention, Figure 5 is a side view showing an embodiment for demolding the flow path using the demolding tool of the present invention.

In the demolding tool of the present invention, as shown in Figs. 4 and 5, a handle portion 20 which can be gripped by hand for demolding the flow path 40 is formed. The handle portion 20 uses a heat-treated metal rod to reduce the overall weight and to have a structural strength corresponding to the bending stress. In addition, when gripping the handle 20 by hand, irregularities can be formed in a rectangular shape to prevent slippage.

And the front end of the handle portion 20 is equipped with a support member 10 is formed integrally with the hook member 11 and the support member 60 for demolding the flow path 40 from the concrete surface. The hook member 11 mounted to the support member 10 is formed with a ring 111 for inserting into the pin hole 42 drilled in the steel frame 41 of the flow path 40.

In addition, the support member 10 is integrally mounted to the front end of the support member 10, and the ground roller 70 is mounted to the rotary shaft 61 formed on one side of the support member 60 by the fastener 80. At this time, the ground roller 70 is a configuration that can be separated and combined by the fixture 80 to be used when replacing or when broken or broken during use. The fixture 80 is composed of any one of the fixing pin 81 or the snap ring 82. When the fixture 80 is a fixing pin 81 is configured to be fixed to the fixing pin 81 in the insertion hole 611 formed in the rotary shaft 61, when the snap ring 82 to the rotary shaft 61 The snap ring 82 is inserted into the formed groove 612 to fix the ground roller 70.

And another side of the supporting member 60 constitutes a presser foot 50 having an insertion hole 51 formed therein for use when demolding the wooden formwork other than the euroform 40 from the concrete surface.

In addition, the lower end of the handle portion 30 is bent inclined to have a wedge portion 20 formed in a wedge shape, and configured to be used as an auxiliary demolding tool when the euroform 40 is demolded.

Hereinafter, an embodiment for demoulding a flow path using the demolding tool of the present invention will be described. In order to construct concrete structures such as retaining walls and columns at the site of civil engineering, architecture, and landscaping works, when concrete is cast and cured with Euroforms 40 fixed by pretai, the concrete surface is finished. The flow path 40 must be demoulded. In this case, when the demolding tool of the present invention is used to demold the euroform 40, first, the handle 20 is heat-treated for reinforcement of bending strength, and then the handle 20 is integrally combined with the handle 20. The ring 111 formed in the hook member 11 of the support member 10 is inserted into the pin hole 42 drilled into the steel frame 41 of the flow path 40 and at the tip of the support member 10. The supporting member 60 mounted is supported on the flow path 40. At this time, the supporting member 60 may support the shaving of the concrete instead of only supporting the flow path 40. Therefore, when supporting the Euroform 40, not the concrete surface, the force is concentrated in one place, so that the ground roller 60 installed on the rotating shaft 61 can be supported while moving to prevent the Euroform 40 from being damaged. .

Then, when the handle 20 is lifted up, since the support member 60 supports the concrete surface or the flow path 40, it serves as a lever. Therefore, the ring 111 of the hook member 11 formed on the support member 10 pulls out the pin hole 42 perforated in the steel frame 41 of the euroform 40 while demonstrating the euroform 40 from the concrete surface. Let's go.

In addition, the presser foot 50 having the insertion hole 51 formed at the other end of the supporting member 60 has a presser foot 50 fixing the wooden formwork when demolding the wooden formwork from the concrete surface instead of the euroform 40. It is used to separate nails. That is, by inserting the insertion hole 51 of the presser foot 50 into the nail head to separate the nail and then demold the wooden formwork.

In addition, the wedge portion 30 mounted on the lower end of the handle portion 30 is primarily a wedge portion between the flow-form 40 and the concrete surface separated from the concrete by demolding by the ring 111 of the hook member 11 Insert the (20) is to play a secondary role to completely demould the flow path 40.
